Similar as reference complex gain calibration, daily gain calibration refers to tuning the "system" amplitude and phase as a function of IF band at a finer level. Typically, daily gain calibration would be carried out three times between two reference gain calibrations every day. We have a routine to retrieve and analyze the daily gain calibration data, named phacal_anal.py. Start from a timestamp (Note: The time of day is important! Make sure to set it to somewhere in the middle of the day, e.g. 15:00 UT)

19:20 UT

Next, as soon as the solar (eclipse) UDB file appears (around 19:20 UT) run the pipeline processing. Change directory to the one where the final eclipse files will be, /data1/dgary/solar/eclipse. Note: the <tab> will complete the filename, but delete the trailing /.:

This will generate the first eclipse map, but it will be a single image of the entire eclipse! There may be some visible indication of the Moon in the image, but perhaps not. To make better images, it will be necessary to run clean on restricted time ranges.
